PURPOSE: Postoperative changes in gut microbiota may occur in patients undergoing Roux-en-Y gastric bypass surgery. In this study, we evaluate the impact of administering probiotic tablets on the gastrointestinal function and metabolic status of these patients. MATERIALS AND METHODS: This double-blinded randomized clinical trial was conducted from 2021 to 2022 on 135 Roux-en-Y surgery candidates. The intervention group underwent the surgical procedure and started receiving probiotic supplements (Familact Co...

Myosteatosis is highly prevalent in metabolic dysfunction-associated steatotic liver disease (MASLD) and could reciprocally impact liver function. Decreasing muscle fat could be indirectly hepatoprotective in MASLD. We conducted a review to identify interventions reducing myosteatosis and their impact on liver function. Non-pharmacological interventions included diet (caloric restriction or lipid enrichment), bariatric surgery and physical activity. Caloric restriction in humans achieving a mean weight loss of 3% only reduces muscle fat...

This case outlines the complications of Roux-en-Y gastric bypass surgery (RYGBS) and demonstrates clinical manifestations of several vitamin deficiencies. We present a 45-year-old female patient who was admitted to our hospital with generalized weakness, anasarca, hypotension, and failure to thrive, a year after she had her RYGBS. After the procedure, she had nausea, vomiting, and diarrhea with progressive inability to tolerate any oral intake. Subsequently, the patient lost over 200 pounds and got bedridden...

BACKGROUND: Bariatric procedures are associated with nutrient deficiencies. Studies show an association between gastric bypass (Roux-en-Y gastric bypass [RYGB]) and hypovitaminosis D as well as hyperparathyroidism, yet few compare RYGB to sleeve gastrectomy (SG), and large long-term analyses are scarce. OBJECTIVE: Evaluate trends of vitamin D and parathyroid hormone (PTH) levels in RYGB and SG. SETTING: National quality register. METHOD: The Scandinavian Obesity Surgery Registry records all bariatric surgeries in Sweden...

Coronavirus Disease 2019 (COVID-19) manifestations range from mild to severe life-threatening symptoms, including death. COVID-19 susceptibility has been associated with various factors, but studies in Qatar are limited. The objective of this study was to investigate the correlation between COVID-19 susceptibility and various sociodemographic and lifestyle factors, including age, gender, body mass index, smoking status, education level, dietary patterns, supplement usage, physical activity, a history of bariatric surgery, diabetes, and hypertension...

Roux-en-Y gastric bypass (RYGB) and gastric sleeve (GS) have been associated with significant reductions in bone mineral density (BMD) and fluctuations in serum levels of calciotropic hormones. These changes pose a risk to bone health. The study assessed the short-term (12 and 24 months) effects of RYGB and GS on BMD and calciotropic hormones. PubMed, Embase, and Cochrane Library databases were searched. Analyses considered follow-up (12 and 24 months) with BMD as main outcome at three sites (femoral neck, total hip, and lumbar spine) and one for each calciotropic hormone (25 OH vitamin D and parathyroid hormone [PTH])...

Outcomes after adjustable gastric banding (AGB) were unsatisfactory and many devices need to be removed for dysphagia. Vitamin C and thiamin deficiency are rare conditions in industrialized countries. Patients undergoing AGB removal (90% for dysphagia) from 2021 to 2023 (laparoscopic 15 and robotic 5) were tested for vitamin C and thiamin levels. Twenty patients (8 m/12 f median aged 56 (range 33.6-79.4) were included. BMI at AGB removal was 39.7 (range 24.4-50.1) kg/m2 . Only 20% of patients had normal thiamin levels, 30% had low levels, 20% were deficient, and 30% were critically low...

BACKGROUND: Maternal obesity is associated with adverse outcome for pregnancy and childbirths. While bariatric surgery may improve fertility and reduce the risk of certain pregnancy-related complications such as hypertension and gestational diabetes mellitus, there is a lack of evidence on the optimal nutritional monitoring and supplementation strategies in pregnancy following bariatric surgery. We aimed to assess the impact of bariatric surgery on micronutrients in post-bariatric pregnancy and possible differences between gastric bypass surgery and sleeve gastrectomy...

INTRODUCTION: A reduction in anti-müllerian hormone (AMH) levels at short-term after bariatric surgery (BS) has been previously described. However, an assessment of ovarian reserve at longer-follow up, and a comprehensive evaluation of the potentially implicated factors has not been reported. DESIGN: Prospective cohort study. MATERIALS AND METHODS: Twenty women aged 18-40 years with BMI 43.95 kg/m2 undergoing BS were studied at baseline (BS0), and at 1 month (BS1), 4 months (BS2), 12 months (BS3), and 24-36 months (BS4) after the surgery...

Nutritional deficiencies represent a prevalent concern among individuals with obesity, stemming from suboptimal dietary habits, chronic inflammation, and preoperative weight reduction efforts. Bariatric surgical interventions, employing either restrictive, malabsorptive or a combination of the two methods, further compound these deficiencies. Commonly observed nutritional deficits following bariatric surgeries include vitamin B12 , vitamin D, thiamine, folate, iron, and protein deficiencies. These deficiencies are further complicated by disparities in healthcare resources and income that distinguish low, medium, and high-income countries...

Wernicke encephalopathy, which is caused by a thiamine deficiency, occurs in 0.8-2% of the population. Only 16% present the typical triad of this disease: nystagmus, confusion and ataxia. We present the case of a postoperative patient with a one anastomosis gastric bypass with reoperation undergoing a Roux-en-Y gastric bypass that begins with confusion and nystagmus on her third postoperative day. The diagnosis of Wernicke encephalopathy is made by imaging, and vitamin B1 is administered with total improvement of nystagmus and altered state of consciousness (lethargy, bradypsychia, bradylalia)...

BACKGROUND: Single anastomosis sleeve ileal (SASI) bypass is a modification of sleeve gastrectomy with transit bipartition (SG + TB). This study aims to assess the safety and efficacy of SASI as a primary metabolic and bariatric surgery (MBS). METHODS: This is a retrospective case series of 30 patients who underwent SASI bypass from January to December 2021. All patients completed at least 12 months of follow-up. RESULTS: Among the 30 patients, 93...

PURPOSE: A potential complication of bariatric surgery is development of nutritional deficiencies. Study aims were to assess prevalence of micronutrient deficiencies in preoperative bariatric patients and to examine for ethnic differences. METHODS: Retrospective analysis of 573 patients that underwent bariatric surgery at Counties Manukau District Health Board was carried out. Mean preoperative levels of albumin, calcium, phosphate, folate, vitamin B12, vitamin D, magnesium, haemoglobin, haematocrit, mean cell volume, mean cell haemoglobin, ferritin, iron, and transferrin were calculated...

To evaluate the efficacy and nutrition of single-anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) in Chinese obese patients in the first postoperative year. Clinical data of 66 obese patients who underwent SADI-S surgery at China-Japan Union Hospital of Jilin University from November 2018 to May 2022 were retrospectively collected. The weight, body mass index (BMI), percentage of excess weight loss (%EWL), and percentage of total weight loss (%TWL) were recorded at 3, 6, and 12 months after surgery...

PURPOSE: To evaluate the influence of vitamin D (VD) concentrations coupled with metabolic phenotypes preoperatively and 6 months after Roux-en-Y gastric bypass (RYGB) on body variables and weight loss. MATERIALS AND METHODS: A longitudinal, retrospective, analytical study comprising 30 adult individuals assessed preoperatively (T0) and 6 months (T1) after undergoing Roux-en-Y gastric bypass. The participants were distributed preoperatively into metabolically healthy obese (MHO) and metabolically unhealthy obese individuals (MUHO) according to the HOMA-IR classification, as well as the adequacy and inadequacy of vitamin D concentrations in the form of 25(OH)D...

PURPOSE: To determine the impact of corrective exercise program applied during the period of rapid weight loss following bariatric surgery on static balance, dietary intake, and body composition. MATERIALS AND METHODS: Participants who had undergone Sleeve Gastrectomy (SG) surgery were divided into as Corrective Exercise Group (CEG), and Control Group (CG). CEG underwent a 12-week supervised corrective exercise program. Body composition and static balance of all participants were assessed before and after the study...

For the diagnosis of a lower-extremity deep vein thrombosis (LEDVT), venous duplex ultrasound is the method of first choice. If a qualified ultrasonography is not timely available, D-dimer testing, and limited ultrasound protocols (point-of-care ultrasound, POCUS) can contribute to therapeutic decision-making when clinical probability is low. A DOAC-based treatment regimen is preferable to a vitamin K antagonist for both acute therapy and secondary prophylaxis of venous thromboembolism (VTE). Treatment with DOACs is unproblematic up to a body weight (BW) of 120 kg or a body mass index (BMI) of 40 kg/m²...

The remission of obesity-related diseases following bariatric surgery appears to result from the reorganization of metabolic and hormonal pathways involving adipokines. This study aimed to investigate the relationship between changes in body adiposity and serum adipokine levels, as well as the association between variations in adiponectin or resistin levels and cardiometabolic risk blood biomarkers before and after Roux-en-Y gastric bypass. A longitudinal and prospective study was conducted with bariatric surgery patients...

Background: A collaborative prescribing (CP) practice model, established by the endocrinologists, pharmacists, and advanced practice nurses, aims to provide for the postoperative monitoring and medical and nutritional management of stable patients after bariatric surgery. Method: Under the CP agreement, endocrinologists refer patients who have undergone bariatric surgery with stable medical conditions to CP practitioners, comprising senior pharmacists and advanced practice nurses. CP practitioners review the patient's weight loss progress, blood test results and vitals, the sufficiency of micronutrient repletion, adherence to supplements and medications, and chronic disease control...
